BACKGROUND OF THE PRESENT INVENTION

Field of the Present Invention

The present invention generally relates to air flow management within anelectronic equipment enclosure, and in particular to, a side-to-sideairflow control system to promote cooling of server equipment thatutilizes side-to-side airflow.

Background

Racks, frames, cabinets and the like for supporting computer and otherelectronic equipment are well known. Such support apparatuses are oftenpartially or fully enclosed, either directly through the use of doorsand panels mounted directly thereon, or indirectly by lining severalsuch apparatuses up in a row such that the sides of each rack areimmediately adjacent another rack.

As is also well known, the electronic equipment mounted therein tends togenerate large amounts of heat that need to be exhausted away from theequipment effectively in order to maintain the equipment in properoperating order or to prevent damage thereto. As equipment has becomemore densely packed with electronics, the quantities of heat havecontinued to increase in recent years. Heat management has thus become asignificant issue confronting today's rack, cabinet, frame and enclosuremanufacturers, the manufacturers of the electronic equipment, and theusers of such equipment.

Each piece of equipment is often enclosed within an individual chassisor housing that includes a location, typically referred to as an exhaustgrille, where air that has been circulated therethrough is exhausted.The heated air is frequently forced or forcibly drawn out of the variousactive pieces of equipment through exhaust grilles of the equipment byinternal fans, often supplemented by separate fans mounted in or on theenclosure. In many pieces of equipment, the exhaust grille is located onthe rear of the equipment, and the equipment is often cooled by bringingcool air to the front of the equipment and exhausted through the rear,often through a door or through exhaust openings in a panel. Otherequipment uses the opposite configuration, wherein cool air is broughtto the rear of the equipment and exhausted through the front; this maybe handled generally similarly as the rear exhaust except that the frontand rear of the cabinet are generally reversed.

However, other equipment is arranged to receive cold air from the sideand to exhaust heated air from the opposite side. For example, a commonpiece of electronic equipment in modern computer networks is a switch.Switches tend to generate a significant amount of heat, and thereforeare of particular concern in exhausting heat from an electronicequipment enclosure, and at least some are manufactured with inlets onone side and exhaust grilles on the other side. Such equipment requiresdifferent treatment than front/rear exhaust equipment.

Currently, in order to remove heated switch exhaust air from the side ofan electronic equipment enclosure, the switch exhaust grille is coupledwith or connected to an individual exhaust duct that is specificallydesigned and sized to fit the particular type of switch being used. Itis important that the switch grille and the exhaust duct inlet aresimilarly sized so that exhaust air is routed outside of the enclosurethrough the duct rather than being released into the interior of theenclosure where it would adversely affect the equipment stored therein.Because of the individual sizing, a different exhaust duct must be usedfor differently sized switches.

One solution has been presented in commonly-assigned U.S. PatentApplication Ser. No. 12/123,453, filed May 19, 2008 and published Dec.25, 2008 as U.S. 2008/0316702 A1 (the “453 Application”), which isincorporated herein by reference. In particular, adjustable fillerpanels are disclosed for more precisely controlling airflow above andbelow side inlets and outlets in certain types of side-to-sideequipment. However, such an arrangement presents only a partialsolution. In particular, such an arrangement does not work well withexhaust ducts located at the top of the enclosure, particularly on thetop panel thereof.

One improved solution has been presented in U.S. Pat. No. 7,957,139,issued Jun. 7, 2011 to Davis et al, but other improvements are believedto be useful, including improvements related to greater customization,improved frame strength, convenience of construction, and the like.Thus, a more versatile, adjustable solution is needed.

In at least some embodiments, the fixed rear panel 82 includesgeometry that matches the geometry of the rear panel assembly 18 and anyother structures that may be located there so as to close anysignificant air gaps that may otherwise exist. For example, theillustrated fixed rear panel 82 includes upper and lower angled portions83 that fit under or over, respectively, the brace structures 44,including their covers 110, that connect the horizontal mounting rails35 to the frame structure 14. The adjustable rear panel 78 is positionedat least partially forward of the fixed rear panel 82 so as to extendfrom the rear of electronic equipment installed in the enclosure 10. Insome embodiments, the adjustable rear panel 78 extends from the rear ofthe electronic equipment and overlaps the fixed rear panel 82, while inother embodiments, the filler panel 76 is installed so as to abut therear of the adjustable rear panel 78, and the filler panel 76 overlapsthe fixed rear panel 82. In other words, in at least some embodiments,the filler panel 76 is only utilized when the adjustable panel 78 andfixed panel 82 do not overlap each other.

The various frame pieces 64,66,68,72,84 are used to build a frameworkthat can be selectively covered with a customizable air dam layer usingportions or entire sheets of the customizable air dam panels 62. In thisregard, FIG. 19 is an isometric view of the electronic equipmentenclosure system 10 of FIG. 2, shown with the customizable air dampanels 62 removed so as to illustrate the air dam framework built usinghorizontal and vertical air dam frame pieces 64,66,68,72,84 while analternative framework can be seen in FIG. 12. In at least someembodiments, the framework is customized by an installer to includerectangular framed openings around the air intake openings of theelectronic equipment that is installed, or is to be installed, in theenclosure, and additional frame pieces are added as necessary to supportthose framed openings and to support larger pieces of air dam panels 62.Horizontal frame pieces 68,72 may have different geometries, and in atleast some embodiments, horizontal frame pieces of different geometriesare used. In this regard, FIG. 20 is an isometric view of a horizontalair dam frame piece 68 of a type used in the side air dam kit 60 of FIG.10, and FIG. 21 is an isometric view of another horizontal air dam framepiece 72 of a type used in the side air dam kit 60 of FIG. 10. Thehorizontal frame piece 72 of FIG. 21 may be preferred for installationat the top or bottom of the large opening to the left of the rear panels76,78,82 in FIG. 19 because they can be attached directly to thefront-to-back members 33, while the horizontal frame piece 68 of FIG. 8may be preferred for installation at intermediate heights between thetop and bottom of the large opening. Likewise, vertical frame pieces64,66,84 may have different geometries, and in at least someembodiments, vertical frame pieces of different geometries are used. Inthis regard, FIG. 22 is an isometric view of a vertical air dam framepiece 66 of a type used in the side air dam kit 60 of FIG. 10.Furthermore, in at least some embodiments, including illustratedembodiments, the adjustable rear panel 78 includes an integrated framepiece 84.

At least some of the frame pieces, such as the frame pieces 66,68,72 ofFIGS. 20-22, are laser cut or otherwise manufactured to enable them tobe easily cut, snapped, or otherwise broken so as to shorten theiroverall length. In at least some embodiments, the cuts are at uniformincremental spacings, such as at 25 mm for horizontal frame pieces and 1RMU for vertical frame pieces. A process of cutting a frame piece isillustrated in FIGS. 23A-23D, wherein the frame piece 66 is held and acutting tool 99 used to break first one side and then the other of anincremental portion of the frame piece 66, and then the correspondingcenter portion is broken and the incremental portion of the frame piece66 is removed. Thus, by supplying a quantity of standardized lengths ofhorizontal and vertical frame pieces, an installer is enabled to createcustomized frameworks by cutting the frame pieces to their desiredlengths. For example, in FIG. 19, a plurality of horizontal frame pieces68 of the original length shown in FIG. 20 have been shortened to spanthe distance between the vertical frame piece on the left of the largeopening and the integrated vertical frame piece 84 on the right of theopening. Similarly, a vertical frame piece 66 of the original lengthshown in FIG. 22 has been separated and shortened and installed betweentwo of the horizontal frame pieces 68 in that opening so as to frame astill smaller rectangle. An alternative arrangement of vertical andhorizontal and vertical frame pieces 68,66 have been installed in thelarge opening to the left of the rear panels 76,78,82 in FIG. 12.

With the framework constructed, one or more customizable air dam panels62 are used to cover all of the framework except the desired openings.FIG. 24 is an isometric view of one of the customizable air dam panels62 of FIG. 10, while FIG. 2 illustrates the placement of a plurality ofair dam panels like that of FIG. 10 on the framework of FIG. 19.Individual air dam panels 62 may be used in their entirety, or may beseparated into customized portions, as desired. In some embodiments, thepanels 62 may be scored into incremental sections. In at least some ofthese embodiments, the spacings are similar to those used for thehorizontal and vertical frame pieces. Overall, each air dam panel 62 maybe cut to length and height, and may be fastened to frame pieces of theframework via apertures penetrating therethrough. In some embodiments,pre-cut apertures may be provided so as to be punched out at desiredlocations; such openings may likewise be provided at uniform spacings.

The side air dam kit 60 is used to segregate cool supply air and heatedexhaust air within an enclosure 10. For example, FIG. 25 is a topcross-sectional view similar to that of FIG. 16, showing the flow of airtherethrough. In the illustrated embodiment illustrated in FIGS. 12 and25, cool supply air enters a front plenum 150 of the enclosure throughperforations in the front panel assembly 16 and also enters a sideplenum 152 of the enclosure 10 through perforations along one side oredge of the rear panel assembly 18. However, it will be appreciated thatcool supply air could alternatively enter only through the front or therear but not both. In the front plenum 150 of the enclosure, air isblocked from flowing along the left side of the equipment by the siderail air dam 30, while panels (not shown) above and below the equipmentblock air from passing over or under the equipment. The air from thefront plenum 150 thus flows into the right side plenum 152 where itjoins the air entering from the rear. Customized air dam panels 62 (notshown in FIG. 12) prevent cool supply air from flowing over or under theequipment from the right side plenum. The cool supply air passes throughthe equipment and gathers in a plenum 154 on the left side of theenclosure before flowing to a rear plenum 156 and then upward through avertical exhaust duct assembly 15 such as that of FIGS. 1 and 2.
